SANDER.

Application filed November 29, 19 13.

To all whom it may concern:

Be it known that we, CHRISTIAN A. J 011N- soN and Hans THISSENIUS,citizens of the United States, residing at Laramie, in the county ofAlbany and State of Wyomin have invented new and useful Improvements inSanders, of which the following is a specification.

This invention relates to sanders such as are used on locomotives forthe purpose of sanding the track, the object of the present inventionbeing to produce either a single or double sander embodying means forregulating the discharge of sand from the box and also preventing thesand from becom ing congested. and closing the discharge orifice or airpassage of the nozzle or nozzles, whereby the sanding device as a wholeis maintained in perfect working condition at all times.

With the above and other objects in View, the invention consists in theconstruction, combination and arrangement of parts, as will hereinafterbe more fully described, illustrated and claimed.

In the accompanying drawings :Figure 1 is a longitudinal section througha sander embodying the present invention, Fig. 2 is a detail perspectiveview of one of the nozzles. Fig. 3 is a detail perspective view of oneof the sieves or screens.

Referring to the drawings 1 designates a sand box of any desired sizeprovided in the opposite ends thereof with sand receiving openings 2each of which is internally threaded as shown at 3 to receive a sandsupply pipe (not shown).

In one side the box 1 is formedwith an internally threaded opening 4 toreceive the externally threaded cylindrical body portion 5 of an airnozzle 6, the outer end of said body being provided with a hexagonalface 7 to receive a wrench for the purpose of adjusting the nozzle inrelation to a discharge opening 8 formed in the opposite side of the boxfrom the nozzle receiving opening 1.

9 designates a lock nut which is threaded upon the body of the nozzlefor the purpose of fixing the adjustment thereof after the properadjustment has been obtained.

The discharge end of the nozzle is of ogee shape as clearly shown inFigs. 1 and 2 and the air-passage 10 therein is of corresponding shapethereby tending to defeat specification of Letters Patent.

the backward movement of any particles of sand or foreign matter throughthe nozzle so as to clog the same. The nozzle is also centrally bored asshown at 11 and internally threaded as at 12 to receive a nozzle body 5is received, the air then passing through a central bore 16 in the sieveand outward through the tortuous passage 10 extending lengthwise of thenozzle.

In Fig. 1 of the drawings we have shown what is termed a double senderor one that is provided with two nozzles for simultaneously dischargingtwo streams of sand upon the rails. It will be understood, however, thata small sand box with a single discharge nozzle may be manufactured ifso desired. The length of the sand box is such, as shown in Fig. 1, thatthe nozzle, notwithstanding the shape thereof, may be turned in order toadjust the distance between the discharge end of the nozzle and the exitopening 8 which receives the discharge pipe through which the sand isconducted to the rails. In this way the amount of discharge of sand maybe regulated. The form of nozzle and air passage extending therethrough,taken in connection with the construction and arrangement of the sieve,checks the sand from working backwardly in the nozzle when the air iscut off and, by reason of the fact that the sieve is contained whollywithin the body of the nozzle, the air pipe or connection may be screwedinto the internally threaded bore of the nozzle without interfering withthe sieve as will be readily understood by reference to Fig. 1.

The nozzle may be easily removed from the box 1 and the sieve may beremoved from the nozzle for the purpose of cleaning out the passagesboth in the nozzle and the sieve, whenever required.

The sieve at its outer closed end is provided externally with a screwdriver nick 17 to facilitate the insertion and removal of said sievewithin the nozzle.
